A Virtual-Reality System for Planning Deep Brain Stimulation Surgery

Medical device, Algorithm, Information & communications technology (ICT)

UNMET NEED

Deep Brain Stimulation (DBS) is a neurosurgical procedure in which electrodes are implanted into the brain to send electrical signals to specific deep areas (e.g., subthalamic nucleus). It is used for the treatment of movement and psychiatric disorders including Parkinson’s disease such as, essential tremor, dystonia, obsessive-compulsive disorder, depression, and epilepsy.

The success of the procedure depends heavily on the accurate placement of the electrode within the optimal therapeutic targets while avoiding vital structures that can cause surgical complications and adverse neurologic effects. The neurosurgeon conventionally uses a software platform showing multiple 2D cut planes of medical images and mentally determines the best implantation trajectory in the 3D brain structure. (i) This method requires a long training process, (ii) takes around 40min for each patient and (iii) is highly prone to human errors.

TECHNOLOGY OVERVIEW

Virtual reality allows intuitive interaction with 3D MRI data, and thus is an excellent fit to navigate complex anatomy for neurosurgical planning. The workflow is as follows:

  1. Patient model preparation, based on MRI images
  2. Voodoo doll interaction strategy to allow precise surgical target selection
  3. Line-of-sight approach with eye-tracking capabilities to determine optimal DBS trajectories.

As a proof of concept, a group of 11 novice users easily and rapidly identified potential DBS trajectories proven to be safe

Currently, the system is fully functional in a lab environment (TRL-4) and is accessible for a demo, on site or through our online platform. Contact us for an appointment.
